Well, there are the rare racing 2.5's with dual plugs, etc. and there are those - like mine - that are normal 2.2L T-motors converted to 2.5L. In the
MM Piston Thread Otto referred to a 251HP 2.5L. He seemed to be talking about the normal single-plug low-compression T-motor, like mine. Except he squeezed an extra 50-60 HP out of it!!!!!!!! I'm not doubting it, but I'd like to know how. Otto?
As far as my existing motor, it is nearly identical to what BA recommends in the Perf. Handbook. It drives very much like an early S motor. Comes on like gangbusters at 5500 RPM's or so and pulls strongly to 7300 RPM. It may lack low-end torque, but I absolutely love high-revving peaky motors like this. It 'feels' very much like a race car. The only car I've ever 'raced' against was a friend's 928S Euro. I easily pulled away from him from around 40MPH all the way to 120MPH or so, then we ran out of road. I was still in 4th gear. 250HP would be absolutely incredible. -- Curt
